Chapter 19. Communications
This chapter surveys three completely different subjects that don’t really fit together, but don’t belong anywhere else either:
Serial communications, otherwise known as your COM port
Remote access services, a set of Windows functions for configuring, making, and breaking dial-up connections to another computer
Sockets, the interface to the TCP/IP protocol and the layer on top of which the various Internet protocols such as FTP and HTTP are built
Each is a subject in its own right, and the techniques are not specific to Python. We’ll show enough to get you started with the right Python extensions and features and try to point you at some of the right sources to learn more.
